Abstract :
This study applied some decent spatial statistical methods and GIS technology to the investigation of the spatial relationship between the locations of DUI Arrests and alcohol retailers in Pensacola, Florida. After exploratory data analysis and testing spatial association based on bivariate J Function, DUI arrests point pattern shows a strong clustering trend around alcohol retainers. A conditional intensity function based on inhomogeneous Poisson process was given to model the spatial association between two of them, and the formula of model was fitted in statistics software called R. According to apply the fitted model, the probability in each position within this area where DUI Arrest might happen was predicted and plotted, which might be helpful to guide government agencies to layout locations of the alcohol retailers.
